The driver accelerated, straddled the middle of the road and turned the car’s headlights on and off, Mancilla said.

When the deputy tried to stop the Camry, the driver sped away at 100 mph during the ensuing 15-minute pursuit on surface streets in Sonoma Valley, Mancilla said.

The driver turned into the Hanna Boys Center on Arnold Drive where deputies used a PIT maneuver to spin the Camry to a stop, Mancilla said.

The driver then drove toward and rammed the pursuing patrol car causing moderate damage to both vehicles, Mancilla said.

Deputies arrested 61-year-old Christopher McRee, of Concord, for assault with a deadly weapon, resisting arrest, evading a police officer and driving on a suspend license. He was booked in the Sonoma County jail in lieu of $30,000 bail.

Deputies were unable to determine why McRee fled the deputy but he was arrested last week for evading police in Alameda County and might have mental health issues, Mancilla said.
